This NPR Indicator podcast interviews a Canadian economist about the economic relationship between the US and Canada, particularly in light of Donald Trump's past rhetoric about Canada becoming the 51st state. The discussion explores the deep economic integration between the two countries, arguing that a merger wouldn't significantly increase overall wealth. The interview highlights three key areas where the US could learn from Canada: its innovative immigration system, universal healthcare system, and affordable, high-quality childcare. The podcast concludes by suggesting that despite political tensions, both nations share similar economic challenges and could benefit from adopting some of each other's successful policies. The Canadian economist's perspective emphasizes the potential for mutual learning and collaboration rather than annexation.
